I've noticed that ever since the last patch that everyone, I mean EVERYONE, it ain't character specific, gets revenge gain even when not being ganked. Let me explain:
Say two people are fighting one person, they're landing hits, guardbreaks, etc. and that person getting double teamed is getting revenge gain as per usual. So naturally, one of the gankers notices this and backs off. They stop attacking, roll away and unlock even... but that person continues to build up revenge as the other ganker continues to land hits.
I notice this all the time. Did they add some sort of AOE for revenge gain or like a timer for additional revenge gain after gankers back off?
